ADA → DOT

What makes ADA -> DOT specific

ADA and DOT live on entirely separate networks - there is no native bridge, no shared standard, and no wrapped-asset shortcut you would actually want to use for a clean swap. Every cross-chain swap here works the same way: you send ADA on the Cardano network, the service liquidates it, and DOT lands on a native Polkadot address (SS58 format, starting with '1'). Confirmation times are reasonable on both ends - Cardano blocks settle in roughly 20 seconds with finality after a few confirmations, and Polkadot finalizes via GRANDPA in 12-60 seconds. End-to-end, expect 5-15 minutes including service processing.

Liquidity for ADA/DOT is decent but thinner than ADA/BTC or ADA/USDT, so quoted rates often route through an intermediate asset. That means spreads matter more than on majors pairs - comparing aggregated rates is where you save real value.

What to check before swapping

• Destination address format: Polkadot uses SS58, not the Kusama or generic Substrate prefix. Sending DOT to a Kusama (KSM) address will lose funds.
• Rate type: floating rates update until execution and usually give a better number; fixed rates lock a quote for 5-15 minutes but charge a wider spread.
• Min/max limits: ADA's lower unit price means small DOT swaps can hit minimum thresholds quickly. Check both sides.
• Refund address: always provide a Cardano return address in case the swap expires or under-funds.
• Memo/tag: neither ADA nor DOT requires a destination tag for personal wallets, but some custodial deposit addresses do - read the deposit instructions.

Practical tip: if you are unstaking ADA first, account for the epoch boundary - rewards from the current epoch will not arrive until the next one closes. Swapping before that final reward lands means leaving a small amount behind.
