On Solana, POST /v1/gas/solana {transaction} with our sponsor as fee payer and pay from $0.03 in Solana USDC. Standard ERC-7677 (pm_getPaymasterStubData / pm_getPaymasterData) at POST /v1/gas; plain EOAs POST {sender, calls} to the same /v1/gas (402 = quote, pay, sign, POST back the signed operation; EIP-7702; already delegated elsewhere: add redelegate:true, reversible). Any EntryPoint v0.8 smart account can bring its own operation: POST {userOperation} unsigned -> 402 -> pay -> sign -> POST back; we dry-run and submit it, no bundler. Price = max($0.03, 1.3× the op's gas cap), cap locked by signature.
