I'm working on using a Dead Man’s Switch to prevent assets being locked in your wallet after your death. Powered by Blockchain!
Note that a smart wallet for Bitcoin-tech doesn't exist, so if you implement a contract, you need to "teach" some wallet how to spend from the template. Dream is to have an universal wallet that can easily import contract templates, things like LibAuth and BitauthIDE were built with that goal, we're getting there!

Any devs have advice on how to create a website similar to memo.cash?
To craft the transactions you'd also need a library, maybe something like https://libauth.org/ or you could craft the transactions by hand by reading on https://documentation.cash/

CHIP: Bounded Looping Operations – enable loops in BCH contracts without increasing processing or memory requirements
I've also written descriptions of all VM operations for Libauth: https://libauth.org/enums/opcodedescriptionscommon.html and https://libauth.org/enums/opcodedescriptionsuniquebch.html

I've been building this "user space" tooling in Libauth (a lightweight, zero-dependency JS/TS library), and I would love to work with anyone interested on building that tooling in other languages/libraries too!

Coming soon to Pokket.cash: SmartBCH support!
Will you soon shut up about BCH being shit against "superior chains" when I point you to the CHIPs such as Native Introspection Opcodes, Bigger Script Integers which allows better smart contract functionality coming in 2022, and PMv3 and Group Tokens which allow better token and transaction formats that are coming in 2023?

What happened to "BSV is law-abiding blockchain and an honest system"?
BSV has no way of storing state or doing anything close to https://github.com/bitjson/pmv3. I'm curious as to what level of fuckery and bloat they're using this time.

CHIP: Ranged Script Numbers (RSN) – a TX integer format which simplifies contracts, reduces transaction sizes, and enables future upgrades
For variable number ranges, all parsing can safely be accomplished using a single 11-byte macro, rather than the minimum 29-byte macro required of VarInt in most cases. (Note, the safe, fully-equivalent VarInt macro is 53-bytes.) This simplification is notable enough to enable use cases which would otherwise be inhibited by parsing constructions causing contracts to exceed VM limits.

Did I summarize the PMv3 transaction proposal correctly?

One nice thing about PMv3 is that the "solution space" is surprisingly limited. Initially it might seem like there are many ways to accomplish the two big goals of PMv3 ("fixed-size inductive proofs" and "VM integer compatibility"), but if you dig deep on any particular element, of the 2 of 3 possible solutions, there's a clear "best choice". (I've tried to document everything in the Rationale section of the spec.) There's probably only one design decision I'm less sure about (the RSN format), but only because the analysis to (dis)prove it is taking me a long time. 😅 (Working on some open source tooling.)

Where is BSV able to run Ethereum smart contracts? Does BSV have an AMM like Uni/Sushi? Does it have decentralized lending like Compound? Decentralized prediction markets like Augur? Does it have ERC20 tokens? What is an example of something BSV can do that ETH specializes in?
Out of curiosity, what would you think about https://github.com/bitjson/pmv3 as a way to enable Ethereum-like smart contracts using a local state contained inside?

Miner-validated tokens on BCH are coming. The powers-that-be will try to split the community on this issue. Do not fall for it!
There are many important use cases for which Group Tokens would require PMv3 (an upgrade which would enable Hashed Witnesses and make CashToken contracts possible in "userland").
-
Jihan Wu hints at an opportunity for BCH: "NFT requires low gas fee to work."
To enable hashed witnesses I proposed PMv3, a minimal v3 transaction format which enables a lot of other use cases like sidechained prediction markets (PM). Group Tokens also cannot support these use cases without hashed witnesses.
What are some alternatives?
When comparing libauth and pmv3 you can also consider the following projects:
bitauth-ide - an online IDE for bitcoin (cash) contracts
cashtokens - A proposal to enable two new primitives on Bitcoin Cash: fungible tokens and non-fungible tokens.
bitcoin-cash - Bitcoin Cash (BCH)
group-tokenization
bch-zce - CHIP-2021-08-ZCE: Zero-Confirmation Escrows – instant, incentive-secure payments on Bitcoin Cash.
sdk - RUN JavaScript SDK
bch-loops - A proposal to enable loops in BCH contracts without increasing processing or memory requirements.
research
bch-vm-limits - By fixing poorly-targeted limits, we can make Bitcoin Cash contracts more powerful (without increasing validation costs).
bitauth-cli - universal identity and message authentication (WIP)
