Atomic swap of colored coins

You can read more about how atomic swaps works here:

color.payment.swap.begin - BeginSwap - Begin swap

  • sender - sender.
  • target - recipient.
  • timestamp - expiration time.
  • alg - hashing algorithm. Supports SHA-512.
  • hash - hash in Base64.
  • id - exchange identifier. Calculated by hash (similar to Acc-ID calculation by public key), but with "SWAP-" prefix.
  • amount - amount transferred.
  • color - coin type.
The command is signed by the account specified in sender.
Possible errors:
  • "Hash algorithm not supported" - unsupported HASH algorithm is set.
  • "Incorrect swap id" - SWAP-ID is set incorrectly.
  • "Swap already exist" - swap with such a hash is already in use.
  • "Incorrect timestamp" - The exchange end time is not set correctly (the time has already expired)
  • "Unknown target account" - there is no recipient's account.
  • "Insufficient number of colored coins on the balance" - insufficient amount of funds on the balance.
  • "The 'amount' field value is out of range" - swap amount was set incorrectly.
Example:
{
...
"type": "color.payment.swap.begin",
"data": {
"alg": "sha-512",
"amount": 1000,
"color": "EON-C-A7CJA-F3PUZ-DKVSK",
