Integrating with Agoric Network ​

The Agoric network builds a blockchain for smart contracts in JavaScript using the cosmos-sdk. Cosmos-sdk is software that provides the widely-used Tendermint/CometBFT consensus and best-in-class support for chain operations like staking and governance. For simplicity of chain integration, the Agoric Network works identically to the Cosmos Hub, except using different parameters (e.g., ubld instead of uatom).

TL;DR for Cosmos-experienced ​

This section points at relevant reference documentation for the underlying cosmos-sdk and CometBFT/Tendermint consensus engine, and summarizes the differences.

The Agoric Network currently uses cosmos-sdk v0.45. The general Cosmos documentation for this version can be found here, including structure andgolang documentation, and REST API documentation.

Use the v0.45.1 version of the REST API for accessing the chain. To use the "Try it out" functionality, change the Base URL to agoric-api.polkachu.com:

The chain can also be accessed via JavaScript using the cosmjs library (and associated tutorials), or using CosmosKit.

Chain resources ​

  • The base network entry points for the Agoric chain are specified in the network config.
  • Additional chain information, including tokens and their logos, gas fee information for wallets, additional entry points, and explorers is maintained in the Cosmos Chain Registry.
  • The source code for the Agoric Network runtime and contracts is in the Agoric open source repository on GitHub.
  • The base unit for staking is ubld (corresponding to uatom for Cosmos Hub)
  • The command utility of the agoric chain is agd (corresponding to simd for the Cosmos Hub).

Tools ​

Building agd ​

The agd command line tool can be built by running the commands as below:

sh
git clone -b community-dev https://github.com/Agoric/agoric-sdk
cd agoric-sdk
SKIP_DOWNLOAD=false ./bin/agd build
export PATH=$PWD/bin:$PATH

To confirm that agd is in your $PATH, execute

agd version --long

Unlike typical cosmos-sdk chains where the daemon is a single executable file, Agoric's use of cosmos-sdk depends on many components of agoric-sdk at runtime. Copying agd to /usr/local/bin or the like is unlikely to produce a working installation. For more detail, see #7825.
