Chaingateway API Reference

The Chaingateway API reference documents a REST API for seven blockchains: Bitcoin, Ethereum, BNB Smart Chain, Tron, Solana, Polygon and Arbitrum. It covers address and wallet creation, native and token transfers and, on six of the seven chains, webhooks. Every request authenticates with a Bearer token.

• Addresses: every chain can create addresses (Bitcoin calls them wallets). Tron, Ethereum, BSC, Polygon and Arbitrum can also import existing ones.
• Transactions: native transfers and token transfers, namely TRC20, TRC721 and TRC10 on Tron, ERC20 and ERC721 on Ethereum, Polygon and Arbitrum, BEP20 and BEP721 on BSC, and SPL on Solana.
• Webhooks: Tron, Ethereum, BSC, Polygon, Bitcoin and Arbitrum register callbacks and list delivered and failed notifications. Solana has no webhook endpoints. Ethereum, BSC, Polygon and Arbitrum also expose a gas price endpoint.
• Authentication: send a Bearer token in the Authorization header. Add X-Network: testnet to switch a request to testnet. Leave it out, or set it to mainnet, to use mainnet.
