Making token transfers efficient, easy while and not reliant on centralized players. Based on more than 100 conducted interviews we've realized there is an issue with transferring tokens, especially NFTs. Respondents usually use one of the marketplaces, their mobile wallet or real die-hard people go via Etherscan. This come's with a couple of important challenges, it takes a lot of time, and a lot of calls, and users don't get a good overview of what is happening.
-We’ve created an optimized way to transfer any tokens (ERC 20/721/1155) and added smartness to either batch transactions of multiple tokens or individual sends. A decentralized, smart, and optimized way to move assets smoothly.
Fetching the asset data of ERC 20/721/1155 across all swosh.cash supported chains via Covalent unified API. One challenge we had was that we were not possible to get metadata because we had to use no-nft-fetch=true but a great support for multichain dapps.
integrated Lens following used as an address book to easily find recipients for your token transfers. Almost like a Lens-transfer ;)
The future of the Ethereum ecosystem is multichain, and polygon has a proven track record of bringing in fast and cheap transaction and a thriving community. Being the home to Lens and newly moved Yoots it’s a chain that would benefit greately from a new and easy way to transfer tokens around community members and for offloading from hot to cold storage.
We want to push this tool on Polygon because the massive community and we believe that we can satisfy its needs! By delivering a better UX and empowering NFT communitys with easier transfers.
Simple and smooth deployment, we also created a faucet for people to easily get their hands on their first BASE NFT via https://swosh.cash/faucet to also help the future base devs to be up and running to try with free mint ERC 20/721/1155.
Great experience of Scroll alphanet: open the docs, check the rpc and we we're done! Only challenge we had was that scroll is not supported by wagmi so we had some small issues with the config. We're strong believers in the growth of scroll zkEVM with lower cost+shorter block times and higher throughput! Looking forward for a etherscan block explorer. Deployed on Scroll as well as integrated with lens! Scroll ♥ Lens | Cross-chain Decentralized Social Media
Even though we tried getting access to the Infura NFT API throughout the hackathon we didn't get access. However, we believe it could be a great complement in getting access to NFT data and not having a single point of failure would be beneficial.
We used Openzeppelin Relayers to deploy the Testnet tokens faucets on different chains

- Sending 1 erc20 token and 1 erc721 will only trigger regular transfer methods
- When sending multiple tokens of the same erc standard we calculate if it is more worth doing approval + batch vs doing multiple single transfers
- When sending multiple tokens of different types we reuse the same gas calculation and make one batch call with erc20 + erc721 + erc1155
NOTE: For each group of transactions we also take into consideration if a user has approved an asset before and if the receiver is single or multiple to save gas while iterating the batch.
