Launchledger is a decentralised, trustless protocol that enables native cross chain swaps between different blockchains. it’s a bit like uniswap, but allows users to swap assets between major blockchains without any wrapped tokens, traditional bridging, and at extremely competitive pricing using the jit amm. it is totally generalised, decentralised, and is live on mainnet.

The largest trading pairs in the cryptocurrency industry are between usd and major crypto assets like btc, eth, sol, and so on – all usually base l1 assets of their own respective blockchains. however, these markets are dominated by centralised exchanges. decentralised exchanges have struggled to compete until recently due to high slippage, gas fees and mev. other alternatives would be to use bridges, but this has largely failed to provide competitive markets and introduces risks which users have become wary of, limiting liquidity and utility. launchledger aims to be the go-to solution for cross-chain swaps. it’s permissionless, easy to use, and decentralised. developers can use it programmatically, and users benefit from better pricing with minimal difficulty. moreover, our user experience will be superior to that of a typical centralised exchange on top of taking capital efficiency to the absolute extreme. this will make it difficult to find a better avenue than launchledger for trading l1 assets and more on-chain launchledger even works without a wallet. you should try it out immediately: https://swap.launchledger.io

Consider a centralised exchange. at its heart, an exchange is a software system which manages private keys (to collect deposits and send withdrawals) in a settlement layer and handles the execution of trades for users in a logically separated accounting layer. launchlegder is not really any different at a high level, except instead of the software being run by a single entity, launchlegder is a consensus-driven software which relies on a quorum of validator nodes. in order to manage wallets, launchlegder uses multi party computation (mpc) (also knows as tss) to govern high-threshold multi signature wallets (100/150) operated through the permissionless validator network. the network requires a constant supermajority to function, and can safely operate so long as an honest superminority remains, which is guaranteed through strong economic security. the state chain defines the amm and accounting ruleset, and the validator software manages individual shares of the multisig wallets owned by the protocol. in a nutshell, the validators operate a virtual amm system that facilitates swaps between the industry’s most liquid and most traded assets.

Launchledger has its own proof-of-stake network that runs its own appchain, called the state chain. to build the state chain, we used substrate, which is the framework used to build polkadot & kusama. launchledger does not intend to become a parachain, and will remain its own sovereign network. the backend validator protocol is written in rust and relies on our own version of the frost threshold signature scheme and custom witnessing system to interact and observe action on all of the chains we are connected to. we also have relatively simple smart contracts which support the network on smart-contract compatible blockchains. the protocol has been fully audited by trail of bits and zellic, and more.

Launchledger’s unique architecture enables interoperability between non-smart contract chains and smart contract chains that goes beyond the simple transfer of assets. this design enables support of almost any chain, evm-compatible, evm-incompatible and blockchains without smart contracts. that unlocks an opportunity to virtually support any asset available on any blockchain.

Yes, anyone can register a node as a validator on launchledger. you will need eth to pay the transaction fee on the ethereum network and $lll to pay the transaction fee on launchledger’s state chain, but a minimum validator bid is now well over $500,000 worth of $lll tokens. more information on the requirements to participate is available. detailed information on setting up a validator could be found in our documentation. other users may be interested in using stlll or other liquid staking derivatives to participate in the network with a much lower barrier to entry.
