# 2.0 Contracts

MAP Protocol v2 uses TSS (Threshold Signature Scheme) for cross-chain asset custody. This page lists the contract addresses and vault information for v2.

> **Note**: Vault addresses may change with each epoch due to TSS key rotation. Use the [tss\_getVault](/api-and-sdk/json-rpc/tss-rpc.md) RPC method to query the latest vault information.

## Query Vault Information

```shell
# Query latest vault
curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"tss_getVault","params":["latest"],"id":1}' \
  https://rpc.maplabs.io

# Query by epoch
curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"tss_getVault","params":["0x1"],"id":1}' \
  https://rpc.maplabs.io
```

See [TSS RPC API](/api-and-sdk/json-rpc/tss-rpc.md) for more details.
