 .sp
 The \fBfundchannel\fR RPC command opens a payment channel with a peer by committing a funding transaction to the blockchain as defined in BOLT #2\&. \fBfundchannel\fR by itself does not attempt to open a connection\&. A connection must first be established using \fBconnect\fR\&. Once the transaction is confirmed, normal channel operations may begin\&. Readiness is indicated by \fBlistpeers\fR reporting a \fIstate\fR of CHANNELD_NORMAL for the channel\&.
