Multi-chain SDK.
One interface, every chain.
The Eraivo SDK gives developers a single, chain-agnostic interface to submit intents, sign non-custodially, and subscribe to real-time events across every supported chain.
Instead of learning chain-specific calldata, RPC quirks, and signing schemes, developers call one interface and let Eraivo resolve the rest.
The same code targets EVM, Solana, and Cosmos; adding a chain does not require rewriting application logic.
The SDK ships the operational concerns most stacks bolt on later:
- —Intent submission with off-chain verification.
- —Non-custodial, KMS-backed signing.
- —Real-time event subscriptions.
- —Typed errors, retries, and idempotency.
Which languages are supported?
The SDK targets TypeScript/JavaScript first; see the developer docs for current language coverage.
Do I write chain-specific code?
No. The SDK exposes one chain-agnostic interface across EVM, Solana, and Cosmos.
How much does it cost to use?
Testnet is free. Mainnet is usage-based at $0.002 per intent, with enterprise contracts available.
