change logic of attestation issuance, to handle fees

[divine-comedian]

We added a resolver contract to enforce an exact amount of ETH to be sent with each attestation using our schema. This will affect users vouching flagging and editing their attestations (deleting/revoking remains unchanged, no fee).

AC

• can successfully vouch to a project
• can sucessfully flag a project
• can successfully edit attestation made to project
• can successfully revoke/delete attestation
• fee of 0.0001 ETH is taken on vouch/flag/edit transactions (in addition to regular gas fee)
• no fee is taken on revoke/delete attestation
• new attestations for vouch/flag/edit shows on relevant project and user attestation history tables

We've changed the approach of this feature now instead we deploy a resolver contract that will collect a specified fee for each attestation made using our schema.

if a user makes multiple attestations the fee also multiplies.

Here is a deployment on Sepolia we can start using right away:

https://sepolia.easscan.org/schema/view/0x87607c7f565dfc1473309a45e7f7d26f0915615258fffd6745fc6238822c108b

for each attestation it is expecting the user to send 0.0001 ETH

You can see some sample data in the tests I ran in foundry here: https://github.com/Giveth/DeVouch-contracts/blob/master/test/testDeployedResolver.t%20copy.sol#L40-L53

To-do

• - Add schema to back-end config add new schema with resolver contract to back-end config, ensure multi-attest works DeVouch-BE#144
• - change attestation flow for vouch/flag/edit to point to new schema
• - add fee amount to attestation data
• - add logic for sending correct amount of eth with transaction

for merging to production"

• - deploy resolver to op mainnet
• - create new schema
• - add schema to backend config and FE environment variables
• - test with foundry script to see if it shows up
• add note in documentation about fees

Test Update

• Can successfully vouch to a project - Pass
• Can successfully flag a project - "Pass"
• Can successfully edit attestation made to project - "Pending"
• Vouch details reflects on Project card - Fail
• Vouch details reflects on Project details page - Fail
• Vouch details reflects on "My Attestation" page - Fail
• Flag details reflects on Project card - Fail
• Flag details reflects on Project details page - Fail
• Flag details reflects on "My Attestation" page - Fail
• Can successfully revoke/delete attestation - Pending
• Fee of 0.0001 ETH is taken on vouch/flag/edit transactions (in addition to regular gas fee) - "Pending"
• No fee is taken on revoke/delete attestation - "Pending"
• New attestations for vouch/flag/edit shows on relevant project and user attestation history tables - "Fail"

After successfully vouching and flagging a project, there is no record of the details on Project card, Project details page as well as my Attestation page
