tBTC has grown ~1,800 BTC in supply as BitGo's wrapped WBTC has fallen by about 3,500 BTC year to date.
Nonetheless, BitGo's wrapped BTC regulary faciliates 100x+ the daily swap volume of tBTC. (Note the Log Scale)
As BitGo prepares to change the custody of WBTC into a multi-jurisdictional system with an industry shaking, yet-to-be determined relationship with Justin Sun & Tron- decentralized alternatives for BTC on Ethereum are in short supply.
Avalanche has its 8-Warden based BTC.b but Ethereum has primarily threshold network's tBTC which uses an honest-majority of 100 nodes to manage BTC on Ethereum.
Past attempts to bring Bitcoin onto Ethereum have struggled:
renBTC was purchased by Alameda Research in 2021 and failed/shut down in 2022.
BadgerDAO's DIGG token rebased itself to peg to BTC's price, but ultimately failed as peg incentives ran out and the DAO gave up on the rebasing concept.
A spin-out of badgerDAO is attempting to create eBTC, an overcollateralized token backed by ETH and staked ETH.
Anytime you use a log scale to compare values on a chart, you should also provide the raw values on the same Y axis.
tBTC is growing, but has a way to go before it takes wBTC's place in DeFi.
