Cross-chain bridge as a service: integrate without building a bridge

Why building a cross-chain bridge is expensive and risky, and how to integrate stablecoin bridging as a service via API, with per-transfer pricing.

Why not build your own bridge

A cross-chain bridge looks simple from outside: "take the token here, deliver it there". Inside it's one of the hardest and riskiest pieces of Web3: contracts on each chain, liquidity to front the payout, confirmation monitoring, failure recovery and refunds. Poorly built bridges are among the sector's biggest exploit targets.

Bridge as a service

Instead of building, you integrate a ready bridge via API. VKX Bridge moves stablecoins across chains with one call and handles everything underneath: creates the order, broadcasts the deposit, tracks confirmation and returns the destination hash. If something fails, there's an automatic refund.

What you get

  • Time to market: integrate in hours, not months.
  • No own-contract risk: the attack surface is VKX's, not yours.
  • Gasless deposit on Polygon: a POL source needs no native coin.
  • Idempotency: safe retry with the same key, no duplicate order.

Predictable pricing

  • Standard: 0.30% + US$0.20 (1 to 3 minutes).
  • Express: 0.30% + US$1.00 (under 1 minute).

No infrastructure cost, no liquidity to maintain. You pay per transfer.

How to start

  • Install: npm install @vkx/bridge
  • Configure your key and call the bridge function.
