Multi-Chain Settlement: How Plaitr Routes Payments Across Every L1 and L2

One of the hardest problems in crypto payments isn't accepting a payment · it's settling it. When your customer pays in SOL on Solana but you want USDC on Ethereum, someone has to bridge, swap, and route that value across chains.

Most merchants don't want to think about this. They just want to see dollars (or stablecoins) in their wallet.

The routing problem

Let's say you're an e-commerce store accepting crypto. A customer wants to pay with MATIC on Polygon. Another pays with ETH on Arbitrum. A third pays with USDT on Tron.

Without a payment rail like Plaitr, you'd need to:

  1. 1.Maintain wallets on every chain
  2. 2.Monitor each chain for incoming payments
  3. 3.Manually bridge tokens to your preferred chain
  4. 4.Swap tokens to your preferred stablecoin
  5. 5.Reconcile everything in your accounting

This is a full-time job. And it doesn't scale.

Best-rate routing

Plaitr's routing engine automatically finds the cheapest path from any input token to your preferred settlement currency. We compare DEX rates across chains, factor in gas costs, and execute the optimal swap · all in one atomic flow.

The merchant experience is simple: you receive the amount you're owed, in the currency you chose, in your wallet. Same day.
