# Bank module

> The bank precompile exposes ERC-20-compatible token transfers plus mint, burn, and authorization methods backed by the SDK x/bank module.

The `x/bank` module in Stable's SDK handles token balances, transfers, and supply. Its EVM surface (the **bank precompile**) wraps this module and adds ERC-20 semantics plus an authorization layer for privileged mint/burn operations. Contracts that need to move tokens on Stable call the precompile directly without deploying their own token implementation.

## What it exposes

The bank precompile provides standard ERC-20 methods:

* `transfer`, `balanceOf`, `totalSupply`
* `approve`, `transferFrom`, `allowance`, `revoke`

These work from any caller. No registration required.

It also provides privileged methods:

* `mint`: mints new tokens and transfers them to an account.
* `burn`: destroys tokens held by an account.
* `multiTransfer`: moves tokens from one sender to many recipients in a single call.

Mint and burn require the caller contract to be registered on the `x/precompile` allowlist via a governance proposal. Governance-token minting is blocked outright. This keeps supply inflation gated to authorized contracts only.

## When to use it

* A DeFi contract needs to move STABLE or USDT0 on behalf of users: call `transfer` or `transferFrom` directly on the precompile.
* A protocol contract mints or burns tokens based on business logic: register through governance first, then call `mint` / `burn`.
* A payments contract needs one-to-many disbursement: call `multiTransfer` in a single transaction instead of looping transfers.

## Where to find the ABI

The full method signatures, event payloads, and authorization flow are in the [Bank precompile reference](/en/reference/bank-module-api).
