| 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 | accrues into the Market price — nothing is paid out | accrues into the Market price — nothing is paid out |
| Read the accrued price | currentPrice(token) / calculateSellPayout | compute from the Asset account (see below) |
| Redemption at maturity | pull via redeemPrincipal() | pull via rwa_exit.claim |
