Query registered pointers and their metadata.

Functions

Function	Description
getCW20Pointer `function getCW20Pointer(string cwAddr) view returns (address addr, uint16 version, bool exists)`	Fetch the ERC-20 pointer for a CW20 contract, plus version + existence flag.
getCW721Pointer `function getCW721Pointer(string cwAddr) view returns (address addr, uint16 version, bool exists)`	Return ERC-721 pointer details for the CW721 contract.
getCW1155Pointer `function getCW1155Pointer(string cwAddr) view returns (address addr, uint16 version, bool exists)`	Return ERC-1155 pointer data for the CW1155 contract.
getNativePointer `function getNativePointer(string token) view returns (address addr, uint16 version, bool exists)`	Resolve the pointer contract for a native denom (e.g., "usei").

Full Solidity Interface


interface IPointerViewPrecompile {
  function getCW20Pointer(string memory cwAddr) external view returns (address addr, uint16 version, bool exists);
  function getCW721Pointer(string memory cwAddr) external view returns (address addr, uint16 version, bool exists);

}

Example


import { ethers } from 'ethers';
 
const POINTER_VIEW = '0x000000000000000000000000000000000000100A';
const ABI = ['function getCW20Pointer(string cwAddr) view returns (address addr, uint16 version, bool exists)', 'function getNativePointer(string token) view returns (address addr, uint16 version, bool exists)'];
 
const provider = new ethers.JsonRpcProvider('https://evm-rpc.sei-apis.com');
const pointerView = new ethers.Contract(POINTER_VIEW, ABI, provider);
 
const [cw20Addr, cw20Version, cw20Exists] = await pointerView.getCW20Pointer('sei1cw20...');
if (cw20Exists) {
  console.log(`ERC-20 pointer deployed at ${cw20Addr} (version ${cw20Version})`);
}
 
const [nativeAddr] = await pointerView.getNativePointer('usei');
console.log('Native pointer for usei:', nativeAddr);

Notes

PointerView is read-only; use the Pointer precompile to create new mappings
Results mirror on-chain state; cache responses client-side to avoid unnecessary RPC calls
Use PointerView to confirm pointer ownership before invoking Pointer-dependent precompiles

Troubleshooting

Error	Cause	Fix
`address(0) returned`	Pointer not registered for the specified contract/denom	Register via Pointer precompile or verify version matrix for support.
`exists = false`	Pointer record never created or removed	Validate mapping history; re-run registration if needed.
