POST /register-donation

called by protocol owner with body:

interface BiobankRegistrationData {
    hla: HLA,
    biobankAddress: string,
    donorAddress: string,
    amounts: number[],
    signature: string,
    genome: string
}

amounts -- array of donation fractions in CC. Example: [10, 5, 5, 2, 2, 2, 2, 2] or [30]
signature -- donor should sign message to prove identity. Check example below
genome -- full genome and donor info

HLA and genome data encrypted by src/encryptor.ts tool. Genome data uploads to IPFS by uploadGenomeToIpfs function. To prevent biobank fraud we need to have signature of made by donor wallet. Signature made WalletConnect library, sample code:

const authenticator = new Contract(
    contractAddress,
    abis.authenticator,
    new ethers.providers.JsonRpcProvider('https://rpc-mumbai.matic.today')
)

let hlaHash = ethers.utils.id(JSON.stringify(hla))
const registrationParametersHash = await authenticator.getRegistrationHash(donorAddress, hlaHash)

connector // from WalletConnect
    .signMessage([account, registrationParametersHash])
    .then(async (signature) => {
        const response = await fetch(platformBackend + `register-donation`, {
            method: 'POST',
            headers: {'Content-Type': 'application/json'},
            body: JSON.stringify({
                hla,
                biobankAddress,
                donorAddress,
                amounts,
                signature,
                genome,
            }),
        })
    })
