Tether ERC-20 to Tether Solana Exchange Rates

Using the supplied block-time assumptions, Ethereum requires 12 × 12 s = 144 s and Solana requires 32 × 0.4 s = 12.8 s, totaling 156.8 s (2 min 36.8 s) for sequential confirmation waits. This calculation excludes initial transaction inclusion and router processing; skipped slots and network conditions can also affect timing. The supplied typical settlement ranges of 5-10 min on Ethereum and 2-4 min on Solana imply 7-14 min if both stages occur sequentially.

The Ethereum ERC-20 deposit incurs gas paid in ETH: gas used × (base fee + effective priority fee), varying with execution cost and congestion. The Solana SPL payout incurs a fee paid in SOL by the payout transaction's fee payer: a standard base fee of 5,000 lamports (0.000005 SOL) per signature plus any priority fee based on the requested compute-unit limit and compute-unit price. Creating a missing recipient USDT associated token account also requires a rent-exempt SOL deposit, recoverable if that account is later closed. Whether payout costs are absorbed or passed through in the quote depends on the provider; routing or service fees are separate from network fees.
