Crystal-Trade or a classic bridge: what is the difference

	Crystal-Trade	Classic bridge
What you receive	native GRAM on TON	Usually a wrapped token (such as WBTC) that has to be swapped later
Wallet connection and approvals	Not needed: you send coins to the order address	Needed: you connect a wallet and sign contract transactions
Coins for fees on TON	Not needed to receive	Often needed to claim funds or move them after the bridge
Time	After the OP Mainnet (Optimism) confirmations; the status is shown on the order page	Depends on the bridge and the load of both networks
Who holds the funds during the transfer	Crystal-Trade, for the duration of the order (with an AML check)	The bridge smart contract or its validators
