A stable 1:1 transfer moves the same stablecoin (USDC, USDT, USDG, USDC.e) between chains. Pricing is predictable and near-1:1 because no swap occurs — the solver delivers the same asset on the destination as the user offered on the source.

​
When to use

  • Bridging USDC between EVM chains
  • Funding a Solana wallet from Base USDC
  • Rebalancing protocol-owned liquidity across chains
  • Any flow where the user holds and wants the same stablecoin on the destination

​
Pricing properties

  • Predictable. Solver fees are tight because there’s no swap risk.
  • Quote-stable. Stablecoin-optimized quotes remain valid longer than general-purpose bridge quotes, reducing failed transactions.
  • Atomic. Either the full amount lands, or the user is refunded. No partial states.

​
Example: Optimism USDC → Base USDC

Via CLI: 
eco-routes-cli publish --source optimism --destination base
# wizard prompts for token (USDC) and amount
Via REST: 
{
  "intent": {
    "route": {
      "source": 10,
      "destination": 8453,
      "tokens": [{ "token": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "amount": "1000000" }]
