xPollinate Cross-chain Bridge Guide

xPollinate is a seamless cross-chain bridge to bridge stablecoins (USDC, USDT, DAI), WBTC and WETH between multiple blockchains including:

• Binance Smart Chain
• Polygon
• xDAI
• Fantom
• Arbitrum One
• Avalanche
• Moonriver
• Fuse

In fact, it is one of our favourite cross-chain bridges with relatively stable operations, low fees (0.05%) and fast transfers (<5 minutes on average).

How the xPollinate bridge works

The xPollinate V2 interface gives users access to NXTP (Noncustodial Xchain Transfer Protocol) of Connext which is a trustless, low cost, and easily extensible base protocol to enable communication between EVM-compatible chains and L2 systems.

As a lightweight protocol, it is used for generalised cross-chain, cross-rollup transactions that retain the security properties of the underlying execution environment without the need to rely on any external validator set.

Here’s an illustration about how it works:
