Generating the Transferlist Contract Code

Standalone Transferlist Contract

An example initial storage:

$ lorentz-contract-transferlist Transferlist init --issuer "\"$FRED_ADDRESS\"" \
  --transferlists "[]" \
  --users "[]" \
  --admin "\"$FRED_ADDRESS\"" \
  --initialStorageType 'address'

Pair (Pair "tz1RwoEdg4efDQHarsw6aKtMUYvg278Gv1ir" { }) (Pair { } "tz1RwoEdg4efDQHarsw6aKtMUYvg278Gv1ir")

To originate the contract:

$ tezos-client --wait none originate contract Transferlist \
  transferring 0 from $FRED_ADDRESS running \
  "$(cat contracts/address_transferlist.tz)" \
  --init "$(lorentz-contract-transferlist Transferlist init --issuer "\"$FRED_ADDRESS\"" \
  --transferlists "[]" \
  --users "[]" \
  --admin "\"$FRED_ADDRESS\"" \
  --initialStorageType 'address')" --burn-cap 2.937

New contract KT1FHaNcQwQt6Ug92iKuFjFs31bQTSDU92Fi originated.
Contract memorized as Transferlist.

$ TRANSFERLIST_ADDRESS="KT1FHaNcQwQt6Ug92iKuFjFs31bQTSDU92Fi"

Populating the contract

Let's populate the contract with users and transferlists.

Adding users

To generate the parameter to add $ALICE_ADDRESS to transferlist 0:

$ lorentz-contract-transferlist Transferlist UpdateUser \
  --newUser "\"$ALICE_ADDRESS\"" --newUserType 'address' \
  --newUserTransferlistId 0

Right (Right (Left (Left (Right (Pair "tz1R3vJ5TV8Y5pVj8dicBR23Zv8JArusDkYr" (Some 0))))))

We can submit the parameter with the following:

$ tezos-client --wait none transfer 0 from $FRED_ADDRESS to $TRANSFERLIST_ADDRESS \
  --arg "$(lorentz-contract-transferlist Transferlist UpdateUser \
  --newUser "\"$ALICE_ADDRESS\"" --newUserType 'address' \
  --newUserTransferlistId 0)"

Since we'll be adding four users, here's a convenient way to add a user:

$ transferlist_add_user(){ tezos-client --wait none transfer 0 from $FRED_ADDRESS to $TRANSFERLIST_ADDRESS \
  --arg "$(lorentz-contract-transferlist Transferlist UpdateUser \
  --newUser "\"$1\"" --newUserType 'address' \
  --newUserTransferlistId "$2")" --burn-cap 1.0 }

Adding transferlists

To generate the parameter to add a transferlist with:

transferlistId: 0
That can transfer to transferlists 0, 2
unrestricted

$ lorentz-contract-transferlist Transferlist \
  SetTransferlistOutbound --transferlistId 0 --outboundTransferlist "[0,2]"

Right (Right (Left (Right (Left (Pair 0 (Some (Pair True { 0; 2 })))))))

As with users, here's a convenient way to add a transferlist:

$ add_transferlist(){ tezos-client --wait none transfer 0 from $FRED_ADDRESS to $TRANSFERLIST_ADDRESS \
  --arg "$(lorentz-contract-transferlist Transferlist \
  SetTransferlistOutbound --transferlistId "$1" --outboundTransferlist "$2" $3)" --burn-cap 1.0 }

Batching the setup

Users and transferlists may be added in any order.

To populate the contract with the following setup:

Users:

$ALICE_ADDRESS: 0
$BOB_ADDRESS: 0
$CHARLIE_ADDRESS: 1
$DAN_ADDRESS: 2

Transferlists:

0: (unrestricted: True, allowedTransferlists: {0, 2})
1: (unrestricted: True, allowedTransferlists: {1})
2: (unrestricted: False, allowedTransferlists: {1, 2})

We can run:

transferlist_add_user $ALICE_ADDRESS 0
transferlist_add_user $BOB_ADDRESS 0
transferlist_add_user $CHARLIE_ADDRESS 1
transferlist_add_user $DAN_ADDRESS 2
add_transferlist 0 '[0,2]'
add_transferlist 1 '[1]'
add_transferlist 2 '[1,2]' --restricted

Here are links to the operations:

`assertTransfers`

Succeed if and only if, for each from and their associated to's in the list, either:

Both
- assertReceivers would succeed for both the from and to userId's
- to's transferlistId is in the set of from's transferlist's set of allowed outbound transferlists
Or both:
- assertReceivers would succeed for the to userId
- The from userId is the issuer's userId

This is equivalent to the following pseudocode:

def assertTransfers(input_list):
  for from, tos in input_list:
    for to in tos:
      if from == issuer:
        assertReceivers [to]
      else:
        assertReceivers [from, to]
        users.get(to) in transferlists.get(users.get(from)).allowedTransferlists

(list %assertTransfers (pair (userId %from)
                             (list %tos userId)))

See FA2's transfer for an example of a similarly batched entrypoint.

Examples

Using the setup from before, suppose the following call to assertTransfers were made:

assertTransfers 
  { Pair "$ALICE_ADDRESS" { "$BOB_ADDRESS", "$DAN_ADDRESS" }
  , Pair "$BOB_ADDRESS" { "$ALICE_ADDRESS" }
  , Pair "$CHARLIE_ADDRESS" { "$CHARLIE_ADDRESS", "$DAN_ADDRESS" }
  }

alice -> bob: alice and bob are on the same transferlist (0), which contains itself in its allowedTransferlists and is unrestricted, so this succeeds
alice -> dan: alice is on a transferlist (0) that contains dan's transferlistId (2) in its allowedTransferlists and is unrestricted, but it fails because dan's transferlist is restricted
bob -> alice: This succeeds by the same logic as alice -> bob: they're on the same unrestricted transferlist that contains its own transferlistId in its allowedTransferlists
charlie -> charlie: This succeeds since charlie's transferlist is unrestricted and contains its own transferlistId in its allowedTransferlists
charlie -> dan: This fails because dan's transferlist (2) is restricted

Thus the above call to assertTransfers will fail.

Here's how to generate it:

$ lorentz-contract-transferlist Transferlist AssertTransfers \
  --userType 'address' --list \
  "{ Pair \"$ALICE_ADDRESS\" { \"$BOB_ADDRESS\"; \"$DAN_ADDRESS\" }; \
  Pair \"$BOB_ADDRESS\" { \"$ALICE_ADDRESS\" }; \
  Pair \"$CHARLIE_ADDRESS\" { \"$CHARLIE_ADDRESS\"; \"$DAN_ADDRESS\" } }"

Left { Pair "tz1R3vJ5TV8Y5pVj8dicBR23Zv8JArusDkYr" { "tz1bDCu64RmcpWahdn9bWrDMi6cu7mXZynHm"; "tz1aHNfXQkBTKUDtkYrZ1iHhAoV3uZYgmkz1" }; Pair "tz1bDCu64RmcpWahdn9bWrDMi6cu7mXZynHm" { "tz1R3vJ5TV8Y5pVj8dicBR23Zv8JArusDkYr" }; Pair "tz1e95DfgHze6hszPbrkdWeVb4vPiDdJWBhF" { "tz1e95DfgHze6hszPbrkdWeVb4vPiDdJWBhF"; "tz1aHNfXQkBTKUDtkYrZ1iHhAoV3uZYgmkz1" } }

To submit the assertTransfers check:

$ tezos-client --wait none transfer 0 from $FRED_ADDRESS to $TRANSFERLIST_ADDRESS \
  --arg "$(lorentz-contract-transferlist Transferlist \
  AssertTransfers --userType 'address' --list \
  "{ Pair \"$ALICE_ADDRESS\" { \"$BOB_ADDRESS\"; \"$DAN_ADDRESS\" }; \
  Pair \"$BOB_ADDRESS\" { \"$ALICE_ADDRESS\" }; \
  Pair \"$CHARLIE_ADDRESS\" { \"$CHARLIE_ADDRESS\"; \"$DAN_ADDRESS\" } }")"
