About USDT
TEDA currency (USDT) is introduced Tether based stable value of money dollar (USD) token Tether USD (called USDT under), 1USDT = US $ 1, the user can always use USDT and USD 1: 1 exchange. Tether company strictly abide by the 1: 1 of the reserve to ensure that every USDT issued a token, their bank account will have a $ 1 funding. Users can query Tether funds platform, to ensure transparency.
Omni Layer is a communication protocol that uses intelligent bit block chain contract credits, and decentralized peer user currency exchange function. Omni Core bit credits its code base is fast, portable Omni layer based on. This implementation does not require external dependencies unrelated Bitcoin Core, and as with other credit bits node, which itself is bitcoin network. It currently supports wallet mode, and can be seamlessly used on three platforms: Windows, Linux and Mac OS. Omni Layer expansion interface disclosed by JSON-RPC.
Tether wallet is a web-based bitcoin block, in this network to build a consensus top network called Omni Layer, the main idea is bitcoin block were stained writing data needs to be stored.

Initialized two minutes after the start to see if the success, or else not output any information, you need to enter a password on the configuration step, the user name omnirpc instead configured user name you bitcoin.conf in:

Check the block synchronization information
Check the synchronization log (refresh):

The number of queries to the current synchronization blocks:
jian@ubuntu:~/omnidata/testnet3$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockcount", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
Since the BTC usdt is based on all test network can query block on the total credits bit test chain: https://www.blocktrail.com/tBTC
Note that only the block sync to the latest balance can be found in purse, to finish the synchronous block, it requires more than 70G hard disk space.
Create a wallet address
jian@ubuntu:~$ curl --user omnirpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["test"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":"n1Axxy3WGwFci1GJffwdY55dRem92GKXAm","error":null,"id":"curltest"}
The return result "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm" is the newly created USDT wallet, purse beginning m represents an address test chains, purse address on bus 1 at the beginning of the chain is generally
Check balances
Bitcoin balance inquiry
jian@ubuntu:~$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getbalance", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
USDT balance inquiries, please address into your wallet
jian@ubuntu:~$ omnicore-cli omni_getbalance "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm" 1
or
jian@ubuntu:~$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "omni_getbalance", "params": ["n1Axxy3WGwFci1GJffwdY55dRem92GKXAm", 1] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
Obtaining the test coin
Can be obtained in the following two test sites in a small number of Bitcoins, used to make USDT transaction fees testing is sufficient, then the block must be synchronized to the latest, otherwise not obtain Balance:
After the credits acquired bits with the following command to the moneyqMan7uh8FqdCA2BV5yZ8qVrc9ikLPtransmission bit USDT one o'clock credits can be tested, each can be obtained 1BTC USDT 100, a transmission USDT10 obtained here 0.1
jian@ubuntu:~$omnicore-cli -testnet sendtoaddress "moneyqMan7uh8FqdCA2BV5yZ8qVrc9ikLP" 0.1
You can find the bitcoin block chain browser btc balance: https://live.blockcypher.com/btc-testnet/address/2MtW8kA68TMrBLZb373WttjHbxfuRNdvHh7/ , but usdt test network can only use the command line to check in your local area finding the block chain browser.
Send transaction
Parameters are from, to, token id, number of transactions, the payment address btc fee
jian@ubuntu:~$ omnicore-cli "omni_funded_send" "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm" "n4VTWrjPV1QaLmM1x8ZtyLiJoFk3KaCAsi" 1 "1" "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm"
JSON-RPC
You can view: https://github.com/OmniLayer/omnicore/blob/master/src/omnicore/doc/rpc-api.md, the need butt programming language, then you can use the api functions and parameters assembled into json data, e.g. balance inquiry herein json is {"jsonrpc": "1.0", "id":"curltest", "method": "getbalance", "params": [] }then submitted these json string as a parameter to the post ip and port node to return the corresponding json results.
