[Feature] Split / Merge Hypercert

[bitbeckers]

Goal

Claim will be minted for a single user maintaining 100% ownership of the claim

User stories

• As a user, I can use the app to split a hypercert consisting of a single fraction to a set of fractional hypercert (on value)
• As a user, I can use the app to split the impact of a hypercert (fraction) to a set of fractional hypercert (on impact)

Technical

This is where the 1155 becomes SFT again. All tokens should have a supply of 1 (NFT) and a value dimension to represent the portion of claim (Fungify)

Split on impact claim

• Hypercert has baseID = 1, ImpactScopeA and ImpactScopeB
• Token11 and Token12 each representing 50% ownership
  *Now split Token11 into separate tokens for ImpactScopeA and ImpactScopeB => generate baseID {2, 3}

In metadata: Ref: token11

• mints Token21

Value = 100% of baseID 2 (but represents 50% of baseId=1, impactScopeA)

• mints Token31

In metadata: Ref: token11 (stored on IPFS)
Value = 100% of baseID 3(but represents 50% of baseID=1, impactScopeB)
