Decentralized finance (DeFi) noticed a document influx from centralized exchanges as crypto customers flocked to self-custody options following the FTX collapse. Over 100,000 Bitcoin (BTC) left crypto exchanges so buyers might keep away from third-party custody. True to the “not your keys, not your cash” mantra of Bitcoin, DeFi solves a wide selection of issues related to centralized entities.
Nonetheless, a number of studies point out DeFi isn’t a fail-safe atmosphere, as high-profile protocol exploits like Wormhole, Nomad and Ronin made headlines in 2022 for the incorrect causes.
Supply: Token Terminal
DeFi exploiters notably goal cross-chain bridges. In actual fact, cross-chain bridge exploits account for greater than half of all DeFi exploits since September 2020, with roughly $2.5 billion misplaced to those assaults. A Chainalysis report reveals that token bridge assaults accounted for over 69% of the overall quantity of crypto stolen in 2022, a transparent indication that bridge exploits are on the rise.
Why do cross-chain bridges fail?
Because the DeFi ecosystem contains a number of blockchains, transferring digital belongings from one community to a different requires specifically designed protocols that work throughout completely different blockchains. Often known as cross-chain bridges or token bridges, these protocols lock customers’ deposited tokens from one chain right into a contract, then problem the equal quantity of belongings to the identical person within the receiving community.
For instance, because the Bitcoin blockchain isn’t instantly appropriate with the Ethereum (ETH) blockchain, the DeFi ecosystem depends on workarounds like wrapped Bitcoin and token bridges to faucet into the liquidity accessible within the Bitcoin ecosystem.
Most bridge protocols use central storage to again belongings on the receiving blockchain, making a goal spot for hackers. The dearth of developer experience in comparison with the complicated nature of making a bridge that works throughout a number of networks causes safety vulnerabilities, making cross-chain bridges the most important assault floor of the DeFi house.
Learn how to make DeFi extra strong
To make DeFi extra resilient to exploits, a brand new strategy removes this weak hyperlink between blockchains. Mintlayer is a layer-2 blockchain on the Bitcoin community that goals to attach its sidechain to the Bitcoin group with as little friction as attainable. Customers can construct any sort of present DeFi software on Mintlayer with out compromising the core fundamentals of safety and decentralization that the Bitcoin group is constructed on.
Mintlayer goals to remove token bridges, the most important assault floor of DeFi, which prices customers billions of {dollars} yearly. As a substitute of wrapped tokens, customers can trade their BTC for tokens on the Mintlayer blockchain by way of atomic swaps. By not requiring any type of cross-chain bridges, wrapped tokens or pegging mechanism to make use of Bitcoin on its blockchain, Mintlayer eliminates the dangers related to bridges and third-party custody.
Talking in regards to the launch of the Mintlayer blockchain, Mintlayer co-founder Enrico Rubboli stated that it took over 18 months of arduous work. He added:
“Mintlayer is house for tasks keen to construct on high of Bitcoin. We’re thrilled by the standard and quantity of responses relating to potential tasks. Individuals need the performance of DeFi, however don’t wish to compromise the safety and ideas of Bitcoin.”
To allow customers entry to their BTC natively on the go, Mintlayer launched a cellular Bitcoin pockets, accessible on each Google Play and the App Retailer.
DeFi ecosystem specializing in Bitcoin
Except for technical improvement, the staff launched the Mintlayer Ecosystem Fund with the objective of constructing a Bitcoin-centric DeFi ecosystem. Tasks can be part of incubator packages, accelerator packages and apply for grants, or apply for direct funding by way of the fund.
The collapse of main centralized organizations like Celsius, Terraform Labs and FTX triggered an exodus from centralized exchanges to decentralized finance and self-custody options in 2022.
If the DeFi ecosystem needs to maintain this new person base, it wants to unravel ongoing points related to the direct interplay between customers and blockchains, beginning with safety — its most crucial facet. Coming again full circle, the reply could lie in making the trail from Bitcoin to make use of in monetary functions as brief and straight as attainable, with Mintlayer.
