Send assets across chains with a single command.
Routes CLI is a terminal tool for publishing cross-chain intents built on the Eco Routes Protocol. You lock a reward on your source chain; competitive solvers race to deliver the result on your destination chain. Supports EVM (Ethereum, Base, Optimism, and more), and Solana.
$ eco-routes-cli publish --private-key 0xYOUR_PRIVATE_KEY
? Select source chain: Base
? Select destination chain: Optimism
? Route token: USDC
? Route amount: 100
? Reward token: USDC
? Reward amount: 101

1. Install globally
npm i -g eco-routes-cli2. Publish your first EVM intent
eco-routes-cli publish --private-key 0xYOUR_PRIVATE_KEYFollow the prompts to select source chain (e.g. Base), destination chain (e.g. Optimism), token, and amounts. Done.
Tip: pass
--sourceand--destinationto skip chain selection prompts.
Prefer not to pass keys inline? Copy .env.example to .env and set EVM_PRIVATE_KEY (or SVM_PRIVATE_KEY for Solana) — the CLI will pick it up automatically.
An intent describes what you want to happen on the destination chain and what reward you're offering to whoever makes it happen. Solvers — independent actors monitoring the protocol — race to fulfill your intent and claim the reward. The faster the solver, the better the deal for everyone.
This is powered by the Eco Routes Protocol. For the full picture of how intents are encoded, published, and proven, see ARCHITECTURE.md.

Private key formats:
| Chain | Format | Example |
|---|---|---|
| EVM | 0x + 64 hex chars |
0xac09...ff80 |
| Tron | 64 hex chars, no 0x |
ac09...ff80 |

| Solana | Comma-separated bytes | 1,2,3,... |
Copy .env.example to .env. All variables except the private keys are optional.
| Variable | Required | Description |
|---|---|---|
EVM_PRIVATE_KEY |
For EVM chains | EVM wallet private key (0x…) |
SVM_PRIVATE_KEY |
For Solana | Solana wallet key (base58, array, or bytes) |
EVM_RPC_URL |
No | Override RPC for all EVM chains |
SVM_RPC_URL |
No | Override Solana RPC (default: mainnet-beta) |
SOLVER_URL |
No | Use a custom solver endpoint for quotes |
QUOTES_PREPROD |
No | Force preprod quote service (set to true) |
PORTAL_ADDRESS_ETH |
No | Override Ethereum portal contract |
PORTAL_ADDRESS_BASE |
No | Override Base portal contract |
PORTAL_ADDRESS_OPTIMISM |
No | Override Optimism portal contract |
PORTAL_ADDRESS_SOLANA |
No | Override Solana portal contract |
See .env.example for the complete list of portal address overrides.
| Issue | Fix |
|---|---|
Private key error |
Check the format matches the chain type — see Private key formats above |
Chain not found |
Run eco-routes-cli chains to verify the exact chain name or ID |
Insufficient balance |
Ensure your wallet has the reward token plus gas on the source chain |
Quote unavailable |
Not all chain pairs have live routes yet — try a different pair |
RPC timeout |
Set a custom RPC endpoint via EVM_RPC_URL / TVM_RPC_URL / SVM_RPC_URL |
