Teller (DEBIT) - No-Collateral Crypto Lending and Credit Protocol

Your Portfolio Is Worth Millions On Paper and Nothing In Your Bank Account#

You hold Bitcoin, Ethereum, and a portfolio you spent years building. Then a real expense shows up and you face the same ugly choice everyone faces: sell at the worst possible moment, or lock up 300% collateral in a DeFi money market and pray the price never dips. And if it does dip, even briefly, an automated liquidation bot sells your position for you. No warning. No conversation. Traditional lenders will not touch you either, because your net worth lives in a wallet they cannot read. Crypto made you wealthy on a screen while leaving you unable to borrow a single dollar against it.

What If Your Wallet Could Build Credit the Same Way Your Bank Account Does#

Teller flips the entire model. Instead of demanding more collateral than the loan is worth, it turns your existing portfolio into actual borrowing power. Borrow against Bitcoin, Ethereum, or tokenized stocks with no margin calls and no price-triggered liquidations. Or skip collateral entirely: pre-qualify with a network of licensed lenders in about four minutes with no hard credit pull, or build a Teller Score that unlocks unsecured on-chain credit directly. This is the credit layer DeFi has been missing since day one, and it is already live and processing real loans.

What does Teller do?#

🔓 No-Collateral Pre-Qualification: Teller lets you check whether you pre-qualify for a real cash loan without pledging a single token. One short form takes roughly four minutes and covers where you live, what kind of loan you want, your employment and income, and your rough credit tier. Teller checks those answers plus your wallet signals against the eligibility rules of a network of licensed lenders and tells you where you stand. Nothing triggers a hard credit pull, and sensitive fields like bank details are never collected at this stage. Loan types span personal loans, debt consolidation, business loans, HELOCs, mortgages, auto purchase and refinancing, and student refinancing.

🛡️ Asset-Backed Loans With No Margin Calls: This is where Teller separates itself from every other crypto lending market. You borrow USDC against assets you already hold, including major crypto like Bitcoin and Ethereum and tokenized stocks like TSLA, and you keep full ownership and full upside without triggering a taxable sale. Most crypto-backed loans draw a price line above your loan and sell you out the instant collateral dips past it. Teller loans are time-based instead of price-based. Terms are fixed for the loan’s window, so a temporary drawdown does not force a sale mid-term. As long as the loan is rolled over or repaid by its action date, your collateral stays exactly where it is.

📊 Teller Score: Teller assigns each wallet a reputation score from 0 to 1000, and that number is the no-collateral borrowing limit in plain terms. A wallet sitting at 600 can draw up to 600 in protocol-native unsecured USDC. The score is built from capped activity categories, each worth up to 200 points: swapping tokens inside Teller, opening collateral-backed loans, completing partner programs surfaced in the matches rail, and referring other wallets that go on to build their own activity. Every points-awarding action is written to an append-only ledger visible on your Score page, so the history behind your credit is fully auditable rather than a black box.

💵 Score-Backed Unsecured Loans: Once your score is built, Teller issues a genuinely unsecured loan on its own books: a 0% interest, 30-day USDC loan with nothing pledged. Three gates keep the system honest. Your identity has to be verified through a completed KYC check, the requested amount cannot exceed your Teller Score, and you cannot have another open Teller loan on that chain. The relationship stays deliberately simple: a higher score means a higher limit, and the limit can never run ahead of the trust a wallet has actually earned.

🔄 Cross-Chain Swaps: Teller has a built-in swap that converts one token into another across chains at the best available on-chain route. It runs on LI.FI, so a single swap can bridge and trade in one step and settle into whatever you actually need, whether that is USDC to repay a loan or collateral to open one. Swapping doubles as the fastest way to build a Teller Score, since every confirmed swap credits points toward the swap category.

📈 Earn Yield: Lenders are not an afterthought here. Teller supports ERC-4626 yield vaults spanning Yearn V3 and Teller supply pools, so you can deposit stablecoins and earn a base APY, then stake the resulting shares separately to earn a reward token on top. Teller lending pools are single-sided and asset-isolated, meaning you deposit one token and earn more of that same token with no dual-asset exposure, no pairing, and no impermanent loss.

🤖 API and MCP Access: Every feature in the Teller app is exposed to other applications through a REST API and through MCP, with 68 capabilities generated from a single definition so the two can never drift apart. Developers can read balances, scores, credit headroom and live loans, and build swap, borrow, repay and rollover flows. Crucially, Teller never holds a private key and never broadcasts anything itself. Your app passes a wallet address and receives ordered unsigned transactions for the user’s wallet to sign. Adding Teller to an AI assistant is as simple as pasting a URL into a connector picker, which opens the door to autonomous financial agents.

🌐 Live Across Chains and Surfaces: Teller runs on Base, Ethereum, Arbitrum, HyperEVM, and Polygon, and it meets users wherever they already are. The same account works in a browser, as an installable home-screen app on iPhone and Android, inside a Telegram Mini App, and inside a Farcaster Mini App.

Ryan Berkun, Founder and Chief Executive Officer

• Founded Teller in 2020 after identifying that decentralized lending had stalled at over-collateralized models and needed a real credit layer to move forward
• Alumnus of the a16z crypto startup school, one of the most selective founder programs in the industry
• Built Web3 infrastructure across three major ecosystems before Teller, holding grants from Tezos, 0x, and Livepeer
• Previously founded and served as CTO of CoinPlan, a cryptocurrency investing and wealth management platform that received multiple acquisition offers
• Founder and board member of Fabrx Blockchain, and a participant in the 0x Ecosystem Acceleration Program
• Served as a mentor at Celo Camp, supporting builders on the mobile-first payments blockchain
• Active angel investor in the crypto sector

Ivan Perez, Co-Founder and Chief Operating Officer

• Co-founded Teller and has led operations since the earliest protocol builds
• Drove the design of Teller’s consumer credit thesis, framing the opportunity against the multi-trillion dollar global debt market rather than the narrow DeFi lending niche
• Led the Chainlink oracle integration that brought real-time price reference data into Teller’s rate calculations
• Architected the Fortune Teller NFT sale, an early and widely covered experiment in using NFTs to bootstrap protocol liquidity while granting holders access to unsecured loans
• Represented Teller publicly across its launch cycle, including the liquidity program and Compound integration announcements

Why This Team Inspires Confidence#

Institutional Backing: Teller has raised from a roster that reads like a who’s who of both crypto and traditional finance. The seed round was led by Framework Ventures with participation from ParaFi Capital and Maven11 Capital. The follow-on strategic round of $6.85M was led by Blockchain Capital and joined by Franklin Templeton, Toyota Ventures, Bessemer Venture Partners, Upstart, Signum Capital, and United Overseas Bank, alongside angels from PayPal, Fundera, and Bison Trails. Getting a legacy asset manager like Franklin Templeton and a corporate arm like Toyota Ventures into the same DeFi cap table is not something that happens by accident.

Six Years of Continuous Building: Teller has been operating as a lending protocol since 2019, which puts it among the longest-running credit protocols in the space. It survived multiple full market cycles, shipped V1 and V2 of its contracts, deployed across Ethereum and Polygon and then Base, Arbitrum and HyperEVM, and evolved from a testnet experiment into a consumer app. Teams that were around before the last bull run and are still shipping after it tend to be building for reasons other than a token launch.

Independently Audited Contracts: The Teller V2 codebase has gone through security review with Sherlock, one of the more rigorous names in Web3 auditing, across audits in 2023 and again in 2024. Sherlock’s model combines designated senior security researchers with open competitive contests, meaning dozens of independent auditors pressure-tested the same code. Teller also carried Sherlock exploit coverage on its smart contracts.

Genuinely Non-Custodial Design: Teller never holds a private key and never broadcasts a transaction on a user’s behalf. Every on-chain action is returned as an unsigned transaction that the user’s own wallet signs. Even the developer API, which partners use to build entire credit products on top of Teller, operates the same way, so there is no point in the flow where a user’s assets sit in Teller’s hands.

Real Volume, Not Just a Roadmap: Teller reports more than $80M in loans processed and over $1.5M in yield generated to date, working with a network of more than 50 lenders. Users have submitted no-collateral loan applications from over 50 countries, and the protocol supports more than 100 assets as collateral without whitelists or gatekeepers. These are numbers from a product people are already using, not projections from a pitch deck.

Deep Integration Footprint: Teller has plugged itself into an unusually wide set of ecosystems, including Hyperliquid for perpetuals alongside borrowing, ShapeShift for best-route swaps across dozens of chains, Robinhood’s new chain for onchain stock portfolios, the XDC Network for XDC-backed lending, and Reya for delta-neutral funding strategies. Each integration is another distribution channel that does not depend on Teller’s own marketing.

What to Know Before You Buy Teller#

1. Binance Alpha Debut

Teller made its exchange debut on Binance Alpha, which is Binance’s curated early-access platform for projects the exchange considers promising enough to put in front of its user base before any broader listing. Alpha inclusion is not a guarantee of a full spot listing, but it does mean the project passed a review process and is now visible to one of the largest trading audiences in crypto. The listing also came with a Binance Alpha Points airdrop event for eligible users.

2. A Product That Already Works

Most tokens launch attached to a whitepaper. Teller launched attached to a live application with real loan volume, real lenders, and real users across more than 50 countries. You can open the app today and pre-qualify for a loan, borrow against Bitcoin, deposit into a yield vault, or check a wallet score. That gap between promise and product is where most crypto investments go wrong, and Teller has already closed it.

3. The No-Margin-Call Advantage

This is the single feature borrowers care about most, and it is structurally different from how competitors work. Aave, Compound and nearly every major money market liquidate positions based on live price feeds, which means a flash wick can cost you your collateral. Teller loans are time-based, so as long as you roll over or repay by the action date, price movement alone cannot take your position. For anyone who has been liquidated on a dip that recovered an hour later, this is the entire pitch.

4. The Credit Layer Narrative

DeFi has already solved trading, stablecoins, payments, perpetuals and over-collateralized lending. Credit is the last major primitive that has not crossed over, and it is by far the largest one in traditional finance. Consumer lending is measured in trillions of dollars annually while DeFi lending remains a rounding error against it. Teller is one of very few protocols positioned directly on that gap with working infrastructure rather than a thesis.

5. Reputation That Compounds

The Teller Score turns ordinary activity into borrowing power. Every swap, every collateralized loan, every completed partner program and every referral pushes the number up, and the number is the limit. This creates something rare in DeFi: a genuine reason for users to keep coming back and to keep their activity on one platform rather than chasing the highest APY of the week. Wallets that build a score have something they cannot easily replicate elsewhere.

6. Built for the AI Agent Era

Teller shipped a full MCP server alongside its REST API, meaning AI assistants can read portfolios, evaluate credit headroom, and construct borrowing or swap transactions for a user to sign. The team also launched Debit, an AI financial agent with access to third-party credit products and on-chain financial services through any MCP client. As autonomous agents move into financial workflows, protocols that already speak that language are positioned to capture that flow first.

7. A Hard Supply Cap

Teller has a fixed maximum supply of 100,000,000 DEBIT, with no mechanism for inflating beyond it. A capped supply means the number of tokens that will ever exist is knowable today, which matters for anyone thinking about long-term dilution rather than short-term price action.

8. Distribution Across Every Surface

Teller is not asking users to change their habits. It works in a browser, as a home-screen app on iPhone and Android, inside Telegram, and inside Farcaster, across Base, Ethereum, Arbitrum, HyperEVM and Polygon. Products that meet users where they already spend time tend to grow faster than products that demand a new one.

How to buy Teller?#

Teller can be purchased directly on Binance through the Binance Alpha section, which is the most straightforward route for most people. Binance is the largest cryptocurrency exchange in the world by trading volume, serving hundreds of millions of users across more than 180 countries, and its Alpha section is a curated space inside Binance Wallet dedicated to early-stage projects that the exchange has reviewed and selected for early access. Buying there means you get institutional-grade liquidity, a familiar interface, and the security infrastructure of a major exchange, all without leaving the app you probably already have installed. If you are setting up for the first time, having some USDT or USDC ready in your Binance account will make the process smoother.

Buy Teller on Binance

If you would rather buy on-chain, Teller is a BNB Smart Chain token and can be swapped on GMGN. To do this, move some BNB from a central exchange like Binance into your GMGN BSC wallet, since BNB is what covers gas on BNB Smart Chain and what you will swap into DEBIT. Once your BNB has arrived, open the Teller token page on GMGN and complete the swap.

Buy Teller on GMGN

GMGN is one of the fastest on-chain trading terminals available, and it is built for people who want to move quickly without sacrificing visibility. It gives you real-time charts, holder distribution, smart money tracking, and contract safety checks all on one screen, so you can see who is buying and how the token is behaving before you commit. Its built-in wallet removes the usual friction of juggling separate applications, and its execution engine is tuned for speed, which matters when you are trading a token in its early phase. For anyone who wants direct on-chain access to Teller with proper analytics behind it, GMGN is a strong place to trade.
