Wallet association on the Sei network ensures the public key becomes known to the chain. Without this step, the chain cannot determine the Bech32 (`sei...`) address or the EVM-compatible (`0x...`) address from one another.

Below are **4 distinct methods** for associating a wallet. Each method differs in terms of security considerations and required actions.

## **Global Constants**

These constants for the `addr` precompile can also be found in the repo [Sei-Chain/precompiles](https://github.com/sei-protocol/sei-chain/tree/44fd60cec6a5ef301df1472431d6db40b382e486/precompiles/addr):

```ts
// Constants for precompile address and ABI
export const ADDRESS_PRECOMPILE_ADDRESS = '0x0000000000000000000000000000000000001004';

export const ADDRESS_PRECOMPILE_ABI = [
{
