1. A computer-implemented method for performing a token escrow swap on a network of nodes, the method comprising:

enabling a broker-dealer node to sign a buy order transaction;

sending a signed buy order transaction with a first cryptocurrency wallet from the broker-dealer node to a token escrow swap node,

5. The method of claim 2 , wherein each of the first cryptocurrency wallet and the second cryptocurrency wallet stores a public and private key of a currency token.

6. The method of claim 2 , wherein each of the first cryptocurrency wallet and the second cryptocurrency wallet is an Ethereum wallet.

7. The method of claim 1 , wherein any unsigned order is created by a market node.

8. A system comprising:

at least one hardware processor; and

at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:

enable a broker-dealer node to sign a buy order transaction;

send a signed buy order transaction with a first cryptocurrency wallet from the broker-dealer node to a token escrow swap node,

wherein the first cryptocurrency wallet includes keys of a buyer node;

fill a buy order of the signed buy order transaction with currency tokens for the token escrow swap node via the buyer node;

for each matching sell order, transfer security tokens to the token escrow swap node via a seller node;

cause, by the token escrow swap node, sending of the security tokens to the buyer node; and

9. The system of claim 8 further comprising:

enable the broker-dealer node to sign a sell order transaction;

wherein the second cryptocurrency wallet includes keys of the seller node;

fill a sell order of the signed sell order transaction with security tokens through the token escrow swap node via the seller node;

for each buy order, transfer currency tokens to the token escrow swap node via the buyer node;

cause, by the token escrow swap node, send of the currency tokens to the seller node; and

for each buy order, cause, by the token escrow swap node, to send security tokens to the buyer node.

10. The system of claim 9 , wherein enabling the broker-dealer node to sign the buy order transaction comprises:

sending attributes of the buy order to a market node;

forwarding an indication of an unsigned token allowance transaction for a buy order and an unsigned buy order transaction;

causing a signed transaction to be sent with a cryptocurrency wallet for currency tokens, wherein a cryptocurrency wallet stores at least one of a public or private key to track or transfer ownership of a currency token; and

upon receiving the signed transaction with the cryptocurrency wallet, signing, by the broker-dealer node, the buy order transaction.

11. The system of claim 9 , wherein enabling the broker-dealer node to sign the sell order transaction comprises:

sending attributes of the sell order to a market node;

forwarding an indication of an unsigned token allowance transaction for a sell order and an unsigned sell order transaction;

causing a signed transaction to be sent with a cryptocurrency wallet for security tokens;

sending a signed sell order transaction with the cryptocurrency wallet to a token escrow swap node; and

12. The system of claim 9 , wherein each of the first cryptocurrency wallet and the second cryptocurrency wallet stores a public and private key of a currency token.

13. The system of claim 9 , wherein each of the first cryptocurrency wallet and the second cryptocurrency wallet is an Ethereum wallet.

14. The system of claim 8 , wherein any unsigned order is created by a market node.

15. A computer-readable storage medium, excluding transitory signals and carrying instructions, which, when executed by at least one data processor of a system, cause the system to:
