Blockchain Infrastructure as an API


Ðapp development has never been easier


Write something to the blockchain

Using the blockchain takes no technical expertise

              curl "http://happycha.in/api/write/text" \
  -u apikey       = "demoKey" \
  -d callback_url = "http://happycha.in/sample/callback" \
  -d contract_id  = "demoContract" \
  -d user_id      = "fbid0124e4f790" \
  -d data         = "Say something to the blockchain"
