Supported Chains

Trident uses Circle CCTP domains as chain identifiers. Query available deployments at runtime:

let client = TridentClientBuilder::new(endpoint).connect().await?;
// Deployments are fetched automatically during connect()

Mainnet Domains

Current mainnet domains include:

Domain	Chain
0	Ethereum
1	Avalanche
2	Optimism
3	Arbitrum
6	Base
7	Polygon

Use the querier’s ListEvmDeployments RPC to get the canonical list with contract addresses.

Querying Deployments

use tonic::transport::Endpoint;
use trident_proto_types::querier_v1;
use trident_proto_types::querier_v1::querier_service_client::QuerierServiceClient;

let channel = Endpoint::from_static("http://your-attester-endpoint:9000")
    .connect()
    .await?;
let mut querier = QuerierServiceClient::new(channel);

let deployments = querier
    .list_evm_deployments(querier_v1::ListEvmDeploymentsRequest {})
    .await?
    .into_inner();

Token Representations

Use GetTokenRepresentations to discover cross-chain token mappings — which tokens on different domains represent the same underlying asset.
