Mint Precompile

The Mint precompile exposes read-only queries against the Sei mint module, letting EVM smart contracts inspect the chain’s token release schedule and the current minter state.

Address

The Mint precompile is located at the following address:

0x0000000000000000000000000000000000001012

Interface

Mint.sol

// SPDX-License-Identifier: MIT

address constant MINT_PRECOMPILE_ADDRESS = 0x0000000000000000000000000000000000001012;

IMint constant MINT_CONTRACT = IMint(MINT_PRECOMPILE_ADDRESS);

interface IMint {
    // Queries
    function params() external view returns (MintParams memory);
    function minter() external view returns (Minter memory);

    // Structs
    struct ScheduledTokenRelease {
        string startDate;
        string endDate;
        uint64 tokenReleaseAmount;
    }

    struct MintParams {
        string mintDenom;
        ScheduledTokenRelease[] tokenReleaseSchedule;
    }

    struct Minter {
        string startDate;
        string endDate;
        string denom;
        uint64 totalMintAmount;
        uint64 remainingMintAmount;
        uint64 lastMintAmount;
        string lastMintDate;
        uint64 lastMintHeight;
    }
}

Methods

All methods on the Mint precompile are read-only view functions. Calling them with a non-zero value reverts.

`params`

Returns the mint module parameters, including the mint denom and the full scheduled token release schedule.

function params() external view returns (MintParams memory);

Returns

MintParams — a struct containing:
- mintDenom — the denomination minted by the module.
- tokenReleaseSchedule — an array of ScheduledTokenRelease entries, each with a startDate, endDate, and tokenReleaseAmount.

`minter`

Returns the current minter state, describing the active release window and the amounts minted so far.

function minter() external view returns (Minter memory);

Returns

Minter — a struct containing:
- startDate — the start date of the current release period.
- endDate — the end date of the current release period.
- denom — the denomination being minted.
- totalMintAmount — the total amount to be minted over the current period.
- remainingMintAmount — the amount still to be minted in the current period.
- lastMintAmount — the amount minted in the most recent mint.
- lastMintDate — the date of the most recent mint.
- lastMintHeight — the block height of the most recent mint.

import "./Mint.sol";

contract MintReader {
    function getMintDenom() external view returns (string memory) {
        IMint.MintParams memory params = MINT_CONTRACT.params();
        return params.mintDenom;
    }

    function getRemainingToMint() external view returns (uint64) {
        IMint.Minter memory minter = MINT_CONTRACT.minter();
        return minter.remainingMintAmount;
    }
}
