Teller protocol API

Teller Protocol is a decentralised lending protocol that enables long-tail lending pools where liquidity providers can deposit assets and earn yield from borrower interest payments.

The protocol operates with a unique architecture that separates lending and borrowing into isolated pools with specific collateral/lending token pairs. Each pool has pre-set terms including collateralisation ratio, APR range, and maximum loan duration.

Key features:

• Long-tail lending pools: Each pool is isolated to a specific lending token and collateral token pair (e.g., USDC/TIBBIR)

• Time-based loans: All loans on Teller are time-based instead of price-based. Price will never cause a loan to default, only expiration

• Liquidation auctions: On default, collateral is transferred to a 24-hour Dutch auction where it is purchased to pay off the loan

• ERC-4626 compliant: Lenders receive vault shares representing their stake in the pool

• TWAP pricing: Uses Uniswap V3 TWAP for collateral price oracles

The protocol is built on TellerV2 which handles the core lending mechanics, with LenderCommitmentGroup_Pool_V2 contract providing the ERC-4626 vault interface for pool-style lending.
