Supported Blockchains

Fystack supports multiple blockchain networks out of the box. You can also add any EVM-compatible chain with a few lines of configuration.

EVM Chains

The following EVM blockchains have been tested and verified by the Fystack team:

Blockchain	Mainnet	Testnet
Ethereum	Ethereum Mainnet	Sepolia
BSC	BNB Smart Chain	BSC Testnet
Polygon	Polygon PoS	Polygon Amoy
Base (L2)	Base Mainnet	Base Sepolia
Avalanche	Avalanche C-Chain	Fuji
Lisk (L2)	Lisk Mainnet	Lisk Sepolia

Add any EVM chain

Any EVM-compatible blockchain can be added by providing an RPC endpoint. See Adding a New Blockchain Network for a step-by-step guide.

Test new chains thoroughly

Adding a new EVM chain should be tested after configuration to make sure deposits, withdrawals, and token detection are working properly before using it with real funds.

Not Yet Supported

The following chains are under integration and not yet supported:

Blockchain	Status
Arbitrum (L2)	Under integration

Non-EVM Chains

Blockchain	Mainnet	Testnet
Tron	Tron Mainnet	Shasta
Solana	Solana Mainnet	Devnet

Non-EVM chain support

Adding new non-EVM blockchain architectures requires custom integration. Contact the Fystack team for guidance on additional non-EVM chains.

Chain Configuration

Each chain type uses a slightly different configuration format in config.yaml:

• EVM chains use providers with http and wss endpoints
• Solana uses rpc_nodes with url
• Tron uses rpc_nodes with url and optional headers (API key for mainnet)

See Configuration Overview for full details on configuring each chain type.
