The KYC Onboarding adapter is a mix between Coupon onboarding and Onboarding adapter.
- Like with Coupon Onboarding, there is no proposals involved in the onboarding process.
- Like with Coupon Onboarding, an attestation (in this case, that you have been KYCed) has to be provided.
- Like with Onboarding, the number of internal tokens minted is linked to the amount contributed.
The only difference between Kyc Onboarding and the two others is that if configured, the funds won't go to the bank but instead directly to an external address.
To join the DAO, any member needs to first get KYCed and then contribute the right amount to get his UNITS. A member can use KYCOnboarding only once, i.e. if he is already a member he cannot use it.
There is no proposal involved here, i.e. if you are eligible to become a member you can join automatically.
kycedMember: The address of the member that has been verified, and is allowed to redeem a coupon to join the DAO.
chunkSize: How many tokens need to be minted per chunk bought.
numberOfChunks: How many chunks need to be created based on the contribution.
unitsPerChunk: How many units (tokens from tokenAddr) are being minted per chunk.
unitsRequested: which internal token to mint
amount: the amount of internal tokens minted
maximumTotalUnits: How many internal tokens can be minted
Accounting to see the amount of a particular internal token that has been minted for a particular applicant. This is then checked against the maxChunks configuration to determine if the onboarding proposal is allowed or not.
Configures the adapter for a particular DAO. The modifier is adapterOnly which means that only if the sender is either a registered adapter of the DAO or if it is in creation mode can it be called. The function checks that chunkSize, unitsPerChunks and maximumChunks cannot be 0.
