How to integrate 2 minutes

1Set it up once (paste the key when prompted):

npx @vkx/bridge init

2Send — Polygon to BSC, with no gas needed on Polygon:

npx @vkx/bridge send --from POL --to BSC --amount 100 --dest 0x...

Sources: BSC and POL · Destinations: BSC, POL, ARB, AVAX, OPT, ETH, BASE · If anything fails, the amount returns to the source wallet on its own.

Fast mode (under 1 minute): add --speed express to the command, or enable it by default on your key in the table above. Cost: 0.30% + US$ 1.00 per transaction — normal mode costs 0.30% + US$ 0.20 and takes 1–3 minutes.

3Track it:

npx @vkx/bridge status VKX-BRIDGE-...
