S.O.S Chain is a fully on-chain parametric fundraising platform for charitable causes. S.O.S Chain makes it possible to create a blockchain-based infrastructure for launching funds to react to disasters and humanitarian crises in a timely and transparent fashion.
Onboarded causes can collect donations in native and ERC20 assets (configurable to accept some or all), while remaining custodian of the collected funds. S.O.S Chain orchestrates the transfer of crypto assets from the donor to the cause's EOA/Gnosis Safe and rewards the donor with a complimentary NFT representing their donation.
SOS Chain also provides an interface for on-chain support requests in alignment with the fund's cause, such as a request for funds to remedy the damage caused by a recent wildfire from a fund with a relevant focus. Any such request will go through a set of checks, determined by the fund's settings, before being finalized successfully or unsuccessfully.
The checks may either be manual (i.e. an approver verifying the need off-chain, then signing with their wallets) or automated (i.e. an oracle communicating with an off-chain API to determine, say, whether a wildfire really occurred in/around the provided coordinates). Upon successful finalization of all checks, based on the fund's settings, the requested support may be automatically transferred, or (in case of a multi-signature Gnosis Safe contract) initiate a blockchain transfer pending signature of other stakeholders.
