Split contract entrypoints:

default

  • Expects unit as parameter
  • Expects some xtz amount attached to the transaction
  • Returns operations with distributed splits to participants
  • Changes storage undistributed ledger
  • Changes storage residuals sum
  • Anyone can call this entrypoint
  • Behaviour depends on threshold settings
  • Some xtz amount might be locked in residuals

This entrypoint allows HicProxy contract to receive xtz and split it among participants. When this contract used as a recepient of xtz (as a seller in the marketplace or as a royalty receiver) it runs logic that redistribute incoming value using participant shares. By default all incoming values automaticly sent to participants, but admin can set threshold that determines the minimal value that will trigger automatic payout to participant. If value is less than threshold it will be kept in contract until it reaches it. If incoming amount can't be split equally between all participants, the residuals left on the contract and will be reused next time contract recieves some payment (during next default call).

withdraw

  • Expects address of the participant that should receive undistributed amount
  • Expects no attached amount
  • Returns operation with this undistributed amount from undistributed ledger
  • Sets undistributed ledger for address to 0n
  • Anyone can call this entrypoint for any address in undistributed ledger

This entrypoint allow participant to withdraw its undistributed earnings if there is some threshold set and participant wants to receive his share before this threshold is reached. Anyone can call this withdraw for anyone, so it is possible to withdraw for a contract if it had no logic to call withdraw by itself, it can be useful for stacked collab contracts.

set_threshold

  • Expects nat with new threshold value
  • Expects no attached amount
  • Changes storage threshold value
  • Only admin can call this entrypoint

This entrypoint changes threshold value that used in default redistribution mechanics. Default value is 0n which means no threshold is set.

execute

  • Expects executeParams which is record of lambda with executableCall and packedParams with bytes payload
  • Might allow to attach some amount to the call
  • Emits operations that encoded in lambda
  • Only admin can call this entrypoint

Allows administrator to make any operation from the contract name (this can be useful to support another marketplaces that can arise in the future). Shortly: this entrypoint allows admin to run any code that does not change contract storage. There are examples of lambdas in the repository, one of which is marketplace V3 swap

To compile lambda you can use docker version of LIGO compiler:

docker run --rm -v "$PWD":"$PWD" -w "$PWD" ligolang/ligo:0.39.0 compile expression pascaligo lambda --init-file "contracts/lambdas/call/marketplaceV3Swap.ligo" > build/tz/lambdas/call/marketplace_v3_swap.tz

Teia / h=n related entrypoints:

mint_OBJKT

  • Expects mintParams that have the same interface that h=n mint_OBJKT entrypoint
  • Expects no attached amount
  • Emits mint operation to mint_OBJKT to the storage minterAddress
  • Only admin can call this entrypoint

When this entrypoint is called all given params redirected to the h=n minter using split-contract name as a Source, so split-contract became creator of the minted objkt. This allows this contract receive and redistribute royalties in the future.

swap

  • Expects swapParams that have the same interface that h=n V2 marketplace swap entrypoint
  • Expects no attached amount
  • Emits mint operation to swap to the storage marketplaceAddress
  • Only admin can call this entrypoint

The same as mint_OBJKT this swap call allows to swap token on V2 marketplace from the name of the collab contract. This entrypoint was not updated to V3 marketplace to keep backward compatibility. This is possible to swap using Teia V3 marketplace with lambda call.

cancel_swap

  • Expects cancelSwapParams that have the same interface that h=n V2 marketplace cancel_swap entrypoint
  • Expects no attached amount
  • Emits mint operation to cancel_swap to the storage marketplaceAddress
  • Only admin can call this entrypoint

This entrypoint allow to cancel swap from V2 marketplace.

collect

  • Expects collectParams that have the same interface that h=n V2 marketplace collect entrypoint
  • Expects no attached amount
  • Emits mint operation to collect to the storage marketplaceAddress
  • Only admin can call this entrypoint

This entrypoint allows to collect other tokens from V2 marketplace.

registry

  • Expects registryParams that have the same interface that h=n registry registry entrypoint
  • Expects no attached amount
  • Emits mint operation to registry to the storage registryAddress
  • Only admin can call this entrypoint

This entrypoint allows to change collab name / description in registry.

unregistry

  • Expects unit as parameter
  • Expects no attached amount
  • Emits mint operation to unregistry to the storage registryAddress
  • Only admin can call this entrypoint

update_operators

  • Expects FA2 update_operators as parameter
  • Expects no attached amount
  • Emits mint operation to update_operators to the storage tokenAddress
  • Only admin can call this entrypoint

This entrypoint allows to make update_operators call from collab contract name which is required to interact from collab contract with another contracts (including marketplaces).

transfer

  • Expects FA2 transfer as parameter
  • Expects no attached amount
  • Emits mint operation to transfer to the storage tokenAddress
  • Only admin can call this entrypoint

This entrypoint allows to make transfers from the collab contract name. It might be useful for airdrops.

Management entrypoints:

update_admin

  • Expects address of new administrator
  • Expects no attached amount
  • Changes storage administrator to new administrator
  • Only admin can call this entrypoint

This can be useful to transfer admin rights to another address.

Onchain views:

Onchain views is feature that was added in hangzhou protocol upgrade. This allows to make read-only synchronous calls to the contract to get some info onchain.

get_shares

  • Expects unit as parameter
  • Returns map with addresses as keys and shares as values for each participant from the contract

get_core_participants

  • Expects unit as parameter
  • Returns set of participants that required to sign to be shown in UI

get_administrator

  • Expects unit as parameter
  • Returns administrator address

get_total_received

  • Expects unit as parameter
  • Returns amount of xtz that was received by this collab during its existance time (might have interesting usecases I suppose)

get_total_shares

  • Expects unit as parameter
  • Return amount of total shares in contract

Errors:

  • MINT_NF: error raised if minter is not properly configured during contract origination
  • SWAP_NF: error raised if marketplace is not properly configured during contract origination
  • REG_NF: error raised if registry is not properly configured during contract origination
  • ADDR_NF: error raised if recipient address is not found
  • FA2_NF: error raised if token is not properly configured during contract origination
  • AMNT_FRBD: error raised if entrypoint is not expecting to receive any amount but gets some
  • NOT_ADM: error raised if entrypoint is expected to be called by admin only and called by anyone else
  • WR_SHARES: error raised during distribution if the sum of shares is not equal to total shares
  • WR_ADDR: error raised if recipient address requested for withdraw have no splits in collab
