Liquidation Penalty

chop()

Returns the liquidation penalty for an asset.

Parameters

The function takes:

• ilk (bytes32) — identifier for a collateral. The values are:

  • MATIC on Polygon Mainnet — 0x63654d4154494300000000000000000000000000000000000000000000000000.

  • rETH on Ethereum Mainnet — 0x4d56545f72455448000000000000000000000000000000000000000000000000.

  • sfrxETH on Polygon Mainnet — 0x4d56545f73667278455448000000000000000000000000000000000000000000.

  • stMATIC on Polygon Mainnet — 0x4d56545f73744d41544943000000000000000000000000000000000000000000.

  • wstETH on Polygon Mainnet — 0x4d56545f77737445544800000000000000000000000000000000000000000000.

The function returns:

• penalty (uint256) — liquidation penalty per collateral. The formula to turn the result into a decimal system number is penalty / 10^18. For example, 1120000000000000000/10^18 = 1.12 = 12%.

Stability/Borrow Fee

ilks()

Returns the stability fee also known as borrow fee; in simple terms, loan rate.

Parameters

The function takes:

• ilk (bytes32) — identifier for a collateral. The values are:

  • MATIC on Polygon Mainnet — 0x63654d4154494300000000000000000000000000000000000000000000000000.

  • rETH on Ethereum Mainnet — 0x4d56545f72455448000000000000000000000000000000000000000000000000.

  • sfrxETH on Polygon Mainnet — 0x4d56545f73667278455448000000000000000000000000000000000000000000.

  • stMATIC on Polygon Mainnet — 0x4d56545f73744d41544943000000000000000000000000000000000000000000.

  • wstETH on Polygon Mainnet — 0x4d56545f77737445544800000000000000000000000000000000000000000000.

The function returns:

• duty (uint256) — stability fee a.k.a. borrow fee per collateral. The formula to turn the result into a decimal system number is (duty ^31536000) - 1 = borrow_fee. For example, 1.000000001243680656318820313^31536000 - 1 = 0.04 = 4%.
