The contracts are described in:

• Page 2 - How to Swap assets  documentation#940
• Page 2 - How to pay Someone documentation#941
• Page 2 - How to create a Vote documentation#942

For each:

• contract
• wallet style test to specify the interface with the front end
• sketch of core eval code

We'll address deployment separately in...

• tooling to deploy / start multiple contracts #15
