Teller (DEBIT) converter and calculator

Teller is a decentralized lending protocol that turns a user’s existing portfolio into borrowing power. Operating since 2019, the protocol supports both no-collateral and asset-backed borrowing, allowing users to access USDC against crypto and tokenized stocks while avoiding traditional margin calls. Teller Pro serves as the consumer-facing application, connecting wallets and other financial accounts to surface lending opportunities and manage borrowing directly on-chain.

A central part of the ecosystem is the Teller Score, a wallet-based reputation system designed to unlock and increase access to no-collateral credit. Alongside lending, Teller also offers cross-chain swaps and developer access through REST APIs and MCP, enabling other applications and AI tools to integrate Teller’s portfolio, credit, borrowing, repayment, and transaction functionality without taking custody of users’ assets.
