Cross-Chain Bridging, stablecoins

• xPollinate:

https://www.xpollinate.io/

• 0.05% fee

• ensure sufficient liquidity for the target token on target chain via Exit Liquidity column

• the greater the xfer amount or the lesser the liquidity, the longer the xfer can take, up to hours

• Anyswap v3:

https://stable.anyswap.exchange/#/swap

• $0.90 flat fee (as of Aug 26)

• ensure exit liquidity on target chain via middle infobox on swap-UI, right-hand side; if you bridge anyway with insufficient liquidity, you'll receive anyUSDX that has to be swapped, after bridging, via their Pool mechanism, choosing Remove

• evo-matic:

https://evo-matic.com/bridge

(BSC <-> Polygon, 0.5% fee) +

https://wallet.matic.network/

(ETH mainnet <-> Polygon, min 3-hour wait)

Cross-Chain Bridging, non-stablecoin

• multichain.xyz:

https://multichain.xyz/

• BSC is hub; feeless to spoke, fee"full" to hub (check minimum-fee carefully, as it's not a %tage; may be better to swap to stables then bridge)

• from BSC out, change to 5 gwei gas works fine

• step-by-step, BIFI example: https://docs.beefy.finance/beefyfinance/faq/how-to-guides/how-to-bridge-bifi-cross-chain

• Anyswap v2:

https://anyswap.exchange/

• uses multichain.xyz as engine

• difficult UI/UX; choose target chain in MetaMask before filling out swap info

• Polygon Bridge :

https://wallet.matic.network/

(runs against ETH mainnet) +

(BTC chain hub, others spokes, poor UX/UI) +

Cross-Chain Bridging via CEX (stablecoins & non-)

• Binance: only MATIC supported (feeless deposit, 0.1 flat-fee withdrawal)

• SwftCoin:

https://swap.swftcoin.com/

(Supports common coins on BSC, HECO, Polygon. For MATIC, only deposits allowed.)

• Only verified email required, instant access without KYC. KYC lifts withdrawal limits ($25K/day?)

• On Wallet tab, can deposit numerous tokens from numerous chains by choosing token(chain) [e.g. BTCB(BSC) or USDC(BSC)] then Deposit to receive address to send to. Swft seems to create unique on-chain addresses for each user on any chain requested.

• Once received in CEX wallet, to reduce later swap fees from 0.2% to 0.1%, you can first swap for USDT(TRON) and then buy minimum $20 of SWFTC in Trade tab.

• Switch to Swap tab then Swap section, and swap for target flavor of any listed token [e.g. USDT(TRON) or WBTC(MATIC) or USDC(MATIC)]. (Ignore DEX section, not working mid-June.)

• Switch back to Wallet tab, search out token you wish to bridge [e.g. WBTC(MATIC) or USDC(MATIC)], then Withdraw for a smallish flat fee (e.g. $1 for USDC) which you can learn beforehand by viewing this UI even prior to depositing.
