Cross-Chain Quick Reference

The two deployments trade the same way. This table maps the trading concepts across chains so you can port an integration from one to the other.

Concept	Ethereum (Base)	Solana
Where you trade	`Market` contract	`rwa_market` program
Token standard	ERC-20, 18 dp	SPL Token-2022
Identify an asset by	token address	SPL mint
Read the price from	`Market.getAsset(token).price`	`Asset` PDA `price_cents`
Price unit	cents (`PRICE_PRECISION=100`)	`price_cents` (same)
Fee unit	basis points	basis points
Settlement currency	`token.payoutToken()`	`TokenMeta.payout_token`
Quote a buy/sell	`calculateBuyCost` / `calculateSellPayout`	compute from `price_cents` + `fee_bps`
Buy	`buy(token, amount, maxCost)`	`buy(amount, max_cost)`
Sell	`sell(token, amount, minPayout)`	`sell(amount, min_proceeds)`
Buy slippage guard	`maxCost`	`max_cost`
Sell slippage guard	`minPayout`	`min_proceeds`
Approval before trading	ERC-20 `approve` to Market	ATAs passed in `Trade` context (delegate pre-set)
Interest payouts	pushed automatically / `claimPayout()`	pushed automatically
Redemption	paid to you automatically	pull via `rwa_exit.claim`
