Online Blockchain Plc announced Umbria's ultra-low-cost liquidity bridge now supports ETH and MATIC in addition to USDT and UMBR. Using Narni the native tokens for the Ethereum and Polygon networks can be transferred exceptionally quickly and cheaply cross-chain. ETH, which was launched first, can be bridged from the Ethereum to Polygon Network for as little as $2.56 in gas, which is significantly less than other bridges. This has caused the Narni Bridge to be adopted rapidly by many DeFi participants and has especially caught the attention of the Zed Run community, who had previously been hampered by prohibitively expensive gas fees. Another considerable advantage of the Narni Bridge is the APY it pays liquidity providers. Its 'Pool and Earn' function (https://bridge.umbria.network/pool/) enables users to lend their MATIC and ETH (and other assets) to the bridge and earn APY when other participants bridge that specific token between networks. Anyone currently providing ETH to the Polygon pool has received up to an astounding 70% APY with no impermanent loss.
